Abstract: The present invention integrates resource allocation between time division duplex (TDD) and frequency division duplex (FDD) in wireless communication systems. A radio network controller (RNC)(204, 208) receives a radio access bearer (RAB) request from a core network or a wireless receive/transmit unit.  The RNC utilizes a TDD-FDD selector (206, 210) to assign radio resources in response to the request. The TDD-FDD selector evaluates various parameters regarding the received RAB request and determines whether it is preferable to assign TDD resources or FDD resources and whether such resources are currently available. Once resources are assigned, system conditions are evaluated to determine whether optimizations may be made to a current resource allocation.

Abstract: A traveling slip assembly of a snubbing unit is supported directly through mechanical fastening of two or more hydraulic actuators to one or more load members extending from a tubular snubbing structure for transfer of snubbing loads to a wellhead. Preferably, the load members are part of a high strength, lightweight unitary load plate which is mechanically fastened to an outer flange on the snubbing structure, and isolated from the wellbore fluids which permits the load plate's material properties to be selected without consideration of corrosion restrictions. More preferably, the hydraulic actuators are flanged and mechanically connected intermediate along their length to the load plate and manufactured so as to ensure proper alignment of the traveling and stationary slip assemblies and the tubular snubbing structure enabling ease of assembly, precise alignment and a lighter overall structure.

Abstract: Un signal reçu est échantillonné pendant une période d'échantillonnage de T + m*(T/n) dans le cadre d'un processus de détermination de phase d'échantillonnage. T désigne le symbole ou la période de débit des éléments du signal reçu, tandis que n désigne le nombre de phases du signal échantillonné, T/n étant la période de résolution de phase, et m, une valeur entière non nulle, soit - n < m < n (par exemple, m =1 ou -1). Par l'échantillonnage du signal reçu pendant la période d'échantillonnage T + m*(T/n), un ensemble d'échantillons de chacune des phases n du signal échantillonné est créé. Pour chaque ensemble d'échantillons, une corrélation est établie entre l'ensemble d'échantillons et un signal de corrélation prédéterminé dans le but de produire un résultat de corrélation. Dès qu'un résultat de corrélation optimale est obtenu par l'opération de corrélation, le signal reçu est échantillonné pendant une période d'échantillonnage T au cours d'une phase associée au résultat de corrélation optimale. Le système présente des avantages, car le suréchantillonnage à un taux d'échantillonnage de n/T est inutile au cours de la détermination de la phase d'échantillonnage, ce qui réduit d'autant les coûts et la consommation d'énergie.
